IMHO the loss of 2 characters doesn't greatly reduce the number of
possibilities, but it DOES greatly reduce the chance of an obscure error
message appearing when you try and make a temp file on a brain dead FS.

BTW.. For 5 character long temp names with + and = the number of possibile
names is 2073071593, without it is 1804229351.

(13% less)
